For example, the cylinder may be made of a deformable material. The liquid absorbed by the absorber may be discharged by such compression or deformation.

In some embodiments, the tank may have air holes that communicate with the outside. In some embodiments, the air holes allow air to flow between the inside and outside of the tank as the amount of liquid contained increases and the absorber is compressed and deformed by a compressor, presser. As a result, for example, the generation of internal pressure in the tank prevents the collection of liquid and the operation of compressing and deforming the absorber from being hindered. In some embodiments, the air holes may be configured to be hermetically sealed. For example, a stopper, a seal, or the like that closes the air hole from the outside of the container may be provided. The air holes can be closed and the inside can be sealed. Thereby, for example, but not limitedly, it is possible to prevent the collected internal liquid from leaking out.

In some embodiments, the state of absorption of the liquid (absorption amount, state of the absorption step of the liquid (completed, incomplete, etc.), etc.) may be determined based on changes in the properties of the absorber.
In some embodiments, the amount of change (eg, expansion) in the volume of the absorber may be used to determine the state of absorption of the liquid. Based on the amount of expansion (length) of the absorber in the tube axis direction, the collected amount may be measured or the completion of the absorption step may be determined. The support may be provided with a scale for measuring the amount of expansion of the absorber. For example, when the absorber expands inside the support, the expansion amount may be measured using the scale of the support. For example, a scale may be provided on a normal outer wall. When the absorber expands to the outside of the support, the expansion amount of the absorber can be measured by using the scale provided on the outer wall of the cylinder. For example, a scale of another member may be prepared, the scale may be applied, and the expansion amount of the absorber may be measured.
In some embodiments, the amount of liquid absorbed may be determined by the discoloration of the absorber. For example, the absorber may contain a substance that discolors upon contact with water. The amount of liquid absorbed may be determined based on the size of the portion of the discolored absorber (eg, the length along the tube axis). The length of the expansion may be measured, for example, using a scale provided on the support. For example, it may be determined that a sufficient amount of liquid has been collected because the entire absorber or the entire portion of the absorber is discolored.
In some embodiments, a plurality of linked absorbers are provided, of which the amount of liquid absorbed may be determined based on the number of absorbers with altered properties. For example, the characteristics (expansion, discoloration, etc.) of the first and second absorbers have finished changing from the tip (the end that is in contact with or close to the object), and the characteristics of the third absorber have begun to change. Therefore, it may be determined that a sufficient amount of liquid has been collected.
In some embodiments, the tank may be graduated. The amount of liquid collected in the tank may be measured using a scale, or it may be determined whether sufficient liquid has been collected.

At least a part or all of the tank may be made of a transparent material whose inside can be optically confirmed from the outside of the tank. The transparent material whose inside can be optically confirmed from the outside of the tank may be, for example, a resin-based material or a glass-based material without limitation.

1 to 3 show the liquid collector 100 according to a certain embodiment. As shown in FIG. 1, the liquid collector 100 includes a collector main body 110 and a compression member 150 as a second cylinder.

The collector main body 110 includes a support 120 as a first cylinder, an absorber 130, and a tank 140.

The support 120 supports the absorber 130. The support 120 is formed in a cylindrical shape extending in the longitudinal direction Da.
The support 120 includes a cylinder 121 extending in the longitudinal direction Da and a stopper (fixing portion) 123. The cylinder 121 has a cross-sectional shape seen from the longitudinal direction Da, for example, one of a circular shape, an elliptical shape, a polygonal shape, and the like.

The stopper 123 is provided at one end of the cylinder 121 in the longitudinal direction Da. The stopper 123 is provided inside the cylinder 121. The stopper 123 is formed in a plane substantially orthogonal to the longitudinal direction Da. The stopper 123 includes a plurality of flow holes 124 communicating with both sides in the longitudinal direction Da. The stopper 123 may be configured by forming a plurality of flow holes 124 in a plate material provided in a plane substantially orthogonal to the longitudinal direction Da. The stopper 123 may be a grid material or a net material provided in a plane substantially orthogonal to the longitudinal direction Da. When the absorber 130 is pressed toward the stopper 123, the absorber 130 abuts on the stopper 123, thereby restricting the movement of the absorber 130 in the longitudinal direction Da. The stopper 123 determines the position of the absorber 130 with respect to the support 120 when the absorber 130 is pressed toward the stopper 123 when the liquid sucked by the absorber 130 is discharged from the absorber 130.

The stopper 123 is arranged on the other side of the longitudinal direction Da from the cylinder end 1211 on one side of the cylinder 121 in the longitudinal direction Da. As a result, the support 120 has a recess 1222 surrounded by the cylinder 121 and the stopper 123 at one end of the Da in the longitudinal direction. The recess 1222 is open toward one side in the longitudinal direction Da.
In some embodiments, the stopper 123 may have protrusions or three-dimensional structures that project towards the absorber 130 described below. With this protrusion, for example, the absorber 130 can be more compressed and deformed, and the liquid can be discharged from the absorber 130 more efficiently.

The cylinder 121 provided with the stopper 123 at one end of the longitudinal Da has an opening 1223 at the other end of the longitudinal Da. An obstruction body 127 is arranged at the end of the support 120 in the longitudinal direction Da. The obstruction body 127 is arranged so as to be removable or openable / closable with respect to the opening 1223.

The absorber 130 is supported by the support 120. The absorber 130 is located at one end of the support 120 in the longitudinal direction Da. The absorber 130 is configured to be able to absorb the liquid in contact with it.
The absorber 130 contains an elastic material. The absorber 130 may be entirely formed of an elastic material. The absorber 130 may be partially formed of an elastic material. The absorber 130 is configured to be elastically deformed when in contact with a liquid collection target. As the elastic material forming such an absorber 130, a material having elasticity and being porous may be used. Examples of such elastic materials include cellulose. The elastic material forming the absorber 130 may be other than cellulose (non-cellulose material).

The absorber 130 is fixed to the support 120. At least a part of the absorber 130 is fixed to the support 120. In some embodiments, the absorber 130 may be fitted into a recess 1222 of the support 120 and substantially supported or fixed by an inner wall.

At least a part of the absorber 130 is housed in the recess 1222. Only a part of the absorber 130 on the support 120 side may be housed in the recess 1222, or the whole may be housed in the recess 1222. The absorber 130 is fixed to the cylinder 121 by the inner wall of the recess 1222. The absorber 130 may be arranged at a distance from the stopper 123 in the longitudinal direction Da, for example. Further, the absorber 130 may be bonded to the stopper 123 by adhesion, welding or the like.

The absorber 130 can be elastically deformed when pressed against the subject or the object, and absorbs the liquid in contact with the absorber 130. As shown in FIG. 2, the absorber 130 expands from the support 120 so as to protrude mainly in the longitudinal direction Da due to the absorption of the liquid.

The tank 140 accommodates the liquid discharged from the absorber 130 when the absorber 130 is compressed. In some embodiments, the tank 140 is formed by the interior of the cylinder 121 of the support 120. The tank 140 defines a liquid storage space 141 between the stopper 123 and the closed body 127 in the cylinder 121. The liquid storage space 141 is configured to be able to store a liquid inside.

The compression member 150 is formed in the shape of a bottomed cylinder. The compression member 150 integrally has a cylindrical outer wall 151 and a pressing plate 153. The tubular outer wall 151 extends in the longitudinal direction Da. The pressing plate 153 is arranged on one end side of the outer wall 151 in the longitudinal direction Da. The pressing plate 153 is provided in a plane substantially orthogonal to the longitudinal direction Da of the outer wall 151. The pressing plate 153 closes one end side of the outer wall 151 in the longitudinal direction Da. The outer side wall 151 has an opening 154 in the longitudinal direction Da on the side opposite to one end side on which the pressing plate 153 is provided. A support 120 and an absorber 130, which are first cylinders, are formed in the outer side wall 151 so as to be insertable from the opening 154 toward the pressing plate 153. As shown in FIG. 3, a support 120 having an absorber 130 at its tip can be inserted inside the outer wall 151 of the compression member 150. The compression member 150 can move in the longitudinal direction Da with respect to the absorber 130.

As shown in FIG. 3, when the support 120 is inserted inside the outer wall 151, the absorber 130 provided at the tip of the support 120 abuts on the pressing plate 153 of the compression member 150. When the support 120 is further pushed in, the absorber 130 is compressed by the pressing plate 153. As a result, the absorber 130 is compressed and deformed, and the liquid 500 absorbed by the absorber 130 is discharged. The liquid 500 discharged from the absorber 130 moves to the liquid storage space 141 of the tank 140 formed in the support 120 through the flow hole 124 formed in the stopper 123. As a result, the liquid 500 absorbed by the absorber 130 is collected in the tank 140. The pressing plate 153 may have a protrusion or a protruding structure that can enter the recess 1222 of the support 120. This makes it possible to efficiently compress the absorber 130.

In some embodiments, the absorber may be maintained in a compressed state. In some embodiments, the collector body or support and the compression member may be configured so that their relative positions are fixed while the absorber is being compressed. For example, the collector body or support and the compression member may have a structure that fits each other. For example, they may be removable and fitted to each other, or they may be non-removably fitted to each other. For example, they may mechanically fit together.

FIG. 4 shows the flow of the liquid collecting method S10 according to a certain embodiment. As shown in FIG. 4, in the liquid collecting method S10, a step S11 for absorbing the liquid 500 into the absorber 130, a step S12 for discharging the liquid 500 from the absorber 130, and a step S13 for accommodating the liquid 500 in the tank 140. , Is equipped.
In the step S11 of absorbing the liquid 500 into the absorber 130, the absorber 130 of the collector main body 110 is brought into contact with the liquid 500 (illustrated in FIG. 3 and the like, hereinafter omitted). In some embodiments, when the liquid collector 100 collects the body fluid as the liquid 500, the absorber 130 is pressed or brought into direct contact with the subject's body fluid-secreting site. The place where the subject's body fluid is secreted by directly pressing the absorber 130 is, for example, not limited to the eyeball, the outer or inner corner of the eye, the oral cavity (for example, sublingual), the nasal cavity, or the surface of the skin. be. In some embodiments, the body fluid secreted by the subject may be contained in a container. In that case, the absorber 130 may come into contact with the body fluid contained in the container to absorb the liquid 500.
